FEATURES :

Telescopic, compact, light-weight : Length : from 230mm to 880mm. Weight : Approx. 155g
High-voltage detectable : The equipment, whether in stretched state is available for voltage detection in high-tension circuits ( 3.3kV, 6.6kV and 24kV) whether the wires involved are naked or insulated.
Low-voltage detectable : The equipment can be used for voltage detection in low-tension circuits ( 80V ~ 600V) by holding the nameplate portion of the detecting head. Before-use check can easily be done by plugging in an AC 100V plug socket, without using a tester.
Easy to recognize indication : Intermittent lighting in red of a high intensity light-emitting diode and intermittent audible sound of an electronic buzzer are readily recongnizable at a full daylight, noisy location.
Waterproof : The detecting head, being tightly enclosed, is free from any trouble due to dust, dirt, water or the like.
Dielectric strength :
( a) Between Sensing tip ~ Grip portion : 50kVAC, 1 min ( The detector has to be stretched) .
( b) Between Sensing tip ~ Nameplate portion : 4kV AC, 1 min.
Construction : Waterproof ( detecting head impervious to water) .
Insulation resistance : Measure the insulation resistance with the high voltage insulation tester. The areas we measure are the same as dielectric strength test.
( a) Between Sensing tip ~ Grip portion : 1kV ( The detector has to be stretched) . The insulation resistance has to be more than 2000M Ohm.
( b) Between Sensing tip ~ Nameplate portion : 1kV. The insulation resistance has to be more than 2000M Ohm.
Leakage current test : Put high voltage on the parts listed below.
( a) Between Sensing tip ~ Grip portion : 50kV AC, 1 min ( The detector has to be stretched) . The leakage current has to be 100uA or less than 100uA.
( b) Between Sensing tip ~ Nameplate portion : 4kV AC, 1 min. The leakage current has to be 100uA or less than 100uA
Meets EN 61010-1, EN50081-1, EN 55082-1, EN 55022, EN 61000-4-2, EN 61000-4-3
This model 276 HD detects the presence of voltage in AC lines. An elongate insulation rod permits checking of high tension circuits at safe distance for voltage.
The equipment is compact, light weight, and easy to handle, and is also available for voltage detection in low-tension circuits.
